finally I booked in El Gouna, a bit expensive but I think I did a gift to me because I saw some amazing descriptions and feedbacks. Fallen in love...
What do you think?

I will be there this week and stay there for 2 weeks, do you have any advice about the kite size? is it worth also to bring 12 or 13 mt kites? I prefer not to rent there

I preferably would leave my big kite at home to avoid traveling to heavy, but if necessary to take all winds I will bring it
I saw you've been there isn't it? hopefully you can advice on kite sizes or best time to kite there along the day

Depends where you go...Egypt is big and has many spots.
Soma Bay is deep (just stay away from some areas with reef)
El Gouna is quiet a walk to the deep water.
Hurghada at the south is deep close to shore.

Hot air (30-40°C). Warm water 28°C. No wetsuit needed.

Wind is hit or miss...can be daily, can be nothing. But, with a Hydro you should be fine!

anyone can recommend a spot&hotel for going with the family? Ideal setup would be an all-inclusive hotel as close to a launch as possible. Ideally with area suitable for both a beginner (daughter on TT) and hydrofoil for me. Thanks!

Go to Hurgada and stay at the Mecure hotel which is a 5 min walk along the beach to Colona water sports it has a killer beach for beginners just upwind of the kite shop and they have a rescue boat . Don't stay at the Magawish it's not that nice . You can store you gear at Colona and it's safe . You can foil right out of colon water sports as long as you stat below the reef or you can foil right out of the Mecure hotel as there is a wind surf shop there.
